2. Description of the Related Art Conventionally, in a dishwasher, as shown in FIG.
As shown in the schematic structure of the example in (a), a door 1 having a single-piece structure is generally provided on the front surface of the main body 1 so that the door 2 can be opened and closed with the lower part as a fulcrum. Since the door 2 occupies a large space X1 in front of the main body 1 when the door 2 is opened in the direction of the arrow, a large installation space is practically required in the front and installed on a kitchen cabinet (not shown). In this case, there is a problem that the opened door 2 hits another facility part such as a water faucet.

Therefore, recently, as shown in FIG. 2B, the door has a folding structure in which two doors 3 and 4 are arranged in series, or as shown in FIG. A structure with two doors 5 and 6 is provided. According to this
One of the lower doors 4 and 6 is opened when the door is opened in the direction of the arrow.
It is clear that the space required by the kitchen is about half the space X2 or less, as shown in Figure (c), and the kitchen space can be effectively utilized without the need for a large space X1 such as the one-door 2. it can.

By the way, in the case where the upper door 3 and the lower door 4 shown in FIG. 2 (b) are folded upward and opened, the lower door 4 and the lower door 4 are opened. Since the structure is provided so as to be foldable, it is inevitable that the door structure easily swings during the opening / closing operation. Further, in the case where the upper door 5 and the lower door 6 shown in FIG. 6C are opened and closed separately by rotating upward and downward, respectively, the respective free end sides (the lower end portion of the upper door 5 and the lower door). It is a door structure that closes one opening so that the upper end of 6) is joined.

Therefore, it is a problem that the two-door structure of this kind is slightly less stable than the one-door structure. Moreover, this kind of two-door structure is usually equipped with a door lock mechanism for surely maintaining the closed state, but since it is difficult or impossible to provide this on the door free end side,
For example, a door lock mechanism is provided in which hook levers 7 (only one is shown) provided on both left and right sides of the lower door 6 in FIG.

However, since the lower doors 4 and 6 are slightly unstable in the opening and closing operation as described above, the lower doors 4 and 6 are not so stable with respect to the two door lock mechanisms located at the positions greatly separated from each other to the left and right.
May not be completely locked. Since this state seems to be a closed state at first glance, the operation is started in an unstable closed state, so it is considered to provide a door open detection means (not shown) in order to avoid this abnormal situation. . However, if an abnormality is detected by the door opening detection means, the operation of the device becomes impossible and it is determined that the device is out of order.

Above the cleaning mechanism 20, a tableware basket 21 shown by a chain double-dashed line in FIG. 2 is slidably accommodated on the shelf 22 and the tableware stored in the tableware basket 21 (not shown). (D) is washed with water sprayed by the washing mechanism 20 and is put in and taken out through the opening 12. In addition, in the main body 11, a water supply device having a water supply valve (not shown) connected to the inside of the cleaning chamber 17 for supplying and discharging cleaning water, a drainage device having a drainage pump to the outside of the machine, and further for drying. Equipped with a blower with a blower.

An operation panel 23 is provided on the lower part of the front surface of the main body 11, particularly on the front surface of the outer box 15 which is substantially flush with the lower door 14 as shown in FIG. On the operation panel 23, various operation keys 24 for, for example, turning the power on / off, a cleaning course selection setting, and the like for the user to perform necessary setting operations, and a display unit 25 for displaying the remaining time and the like. Is equipped with. And on the back side of this operation panel 23,
As shown in FIG. 3, a control device 26 including, for example, a microcomputer is provided, and based on an operation input of the operation panel 23, various control processes are performed by the control device 26 according to a program stored in advance. I try to control the movement.

The upper door 13 and the lower door 14 having the above-described upper and lower two-door structure are specifically configured as follows. First, as shown in FIG. 3, the upper door 13 has the left and right end portions of the upper side portion (only one right end portion is shown) of the main body 11
It is supported by a hinge member 27 extending from and is rotatably attached in the vertical direction about a shaft 28. In FIG. 2, the hinge member 27 is pivoted upward to open as shown in the open state ( In addition, a plurality of identical components such as the hinge member 27 are
One component will be described as shown in FIG. 3).

Further, a torsion coil spring 29 is wound around the shaft 28, and its elastic force functions as a biasing means for biasing the upper door 13 in the opening direction. That is,
This torsion coil spring 29 has one end at a state where sufficient elastic force is accumulated when the upper door 13 is in the closed state.
The hinge member 27 is engaged and held by the fixed hinge member 27, and the other end of the hinge member 27 is mounted in a state of being directed upward from the center of the rotating shaft 28 on the upper door 13 side (closed state). On the other hand, the lower door 14
The left and right end portions of the lower side portion (only one right end portion is also shown) are respectively connected to the main body 11 by the hinge member 30 and the shaft 31.
It is mounted rotatably in the vertical direction, and in FIG. 2, it is pivoted downward to open to a substantially horizontal position as shown in the opened state.

Then, the double doors 1 which are opened and closed as described above.
3, 14 are configured to be opened and closed by interlocking with each other by an interlocking mechanism 32 shown in FIG. That is, the interlocking mechanism 32 is
The upper door 13 and the lower door 14 are provided in cooperation with each other. First, when the upper door 13 side is described, the upper arm 33 is attached and fixed to both left and right end portions (only one of which is shown and described), and the rear side thereof. One end of the wire 34 is connected to the other end protruding from. On the other hand, a lower arm 35 is connected and fixed to the lower door 14 below both left and right ends (only one is shown), and the other end of the wire 34 is connected to the other end protruding to the back side thereof.

However, these upper and lower arms 33, 35
The other end protruding from each of the doors 13 and 14 is housed between both side walls of the inner box 16 and the outer box 15, and therefore both doors 13 and 1 are
When 4 rotates, both arms 33 and 35 simultaneously move to the respective shafts 28,
It rotates about 31 and the long hole 4 on the front surface of the main body 11 shown in FIG.
Enter and exit 2a and 42b. The wire 3 connected to each of the upper and lower opposing arms 33 and 35.
4 is stretched through a plurality of guide rollers 36a to 36d on the way, and is always kept in a predetermined tension state by a tension pulley 37, so that the wire 34 is guided by the guide roller 3a.
6a to 36d are prevented from being unintentionally removed, and thus the interlocking mechanism 32 is configured.

Therefore, according to such an interlocking mechanism 32, for example, the lower door 14 is rotated from the closed state shown in FIG.
The operation of reaching the open state will be described. The lower arm 35 connected to the lower door 14 also rotates about the same shaft 31, and the other end to which the wire 34 is connected rotates in the upward arrow A direction. Accordingly, the wire 34 is loosened, so that the upper door 13 integrated with the upper arm 33 starts to rotate upward due to the elastic force of the torsion coil spring 29 that urges in the opening direction, and finally becomes. The upper door 13 is opened.

On the other hand, when the lower door 14 is rotated in the closing direction from the open state, the wire 34 is pulled downward by the rotation of the lower arm 35 (direction opposite arrow A), and the upper arm 33 is rotated. Is pulled to the main body 11 side. As a result, the upper door 13 in the open state can be rotated and closed against the elastic force of the torsion coil spring 29 as the biasing means. As described above, since the upper door 13 is urged in the opening direction by the urging means, in order to keep the door closed state shown in FIG.
Therefore, a door lock mechanism 38 for holding the interlocking lower door 14 in a closed state is provided.

The door lock mechanism 38 is provided on both side portions (only one of which is shown and described) extending between the lower door 14 and the main body 11. Specifically, in particular, as shown in FIG. 3, a hollow lower door 14 has a base shaft 39 rotatably supported by a horizontal shaft extending in the left-right direction, and has both end portions (only one end). The hook levers 40 are integrally formed with each other. This hook lever 40
Has a hook portion 40a formed downward at the tip thereof, and the hook portion 40a is constantly urged downward by a tension coil spring 41. However, this hook 40
The front end portion having a protrudes to the back side of the lower door 14 and the main body 11
The lower door 14 is locked and held in its closed state by entering inward from the front surface and engaging with the body 11 side, and the switch case 43 is provided on the body 11 side (details will be described later).
In order to engage and hold the hook portion 40a by utilizing the
Formed facing the front.

The door lock mechanism 38 having such a structure
Is provided with a lock release push button 44. The push button 44 is provided integrally with the base shaft 39 so as to hang downward from a central portion of the push rod 44 and partially protrudes forward from the lower door 14. It is formed in the shape. Further, a handle 45 suspended in a horizontal axis state is provided on the front surface of the lower door 14 in the vicinity of the upper portion of the push button 44, and the user holds the handle 45 while pushing the push button 44 with one hand. The lower door 14 can be operated by opening the door.

Now, the switch case 43 will be described. This constitutes a so-called door opening detecting means 46 for detecting that the lower door 14 is in an open state, and a micro switch is provided in the switch case 43. 47 and its actuator 48. That is, one end (the left end in the figure) of the swingable actuator 48 is in a positional relationship where it abuts and engages with the step portion 40b at the tip of the hook lever 40, and the other end turns on / off the micro switch 47.
Turns off. In addition, when the micro switch 47 is turned on and it is detected that the door is open, LEDs 49, which are light emitting elements, are displayed on the left and right sides of the front surface of the lower door 14 as a means for displaying the detection result. It is arranged so that it lights up and is displayed.

However, each LED 49 is located in the vicinity of the left and right door lock mechanisms 38 located inside the lower door 14,
Based on the lighting display of the LEDs 49 located on the left and right, the operation (locked) state of the door lock mechanism 38 corresponding thereto can be determined, and the open / closed state of the lower door 14 can be known. Further, the detection result of the door opening detection means 46 having such a configuration is input to the above-mentioned control device 26, and the operation control is performed in accordance with this.

As shown in FIG. 1, an exhaust port 50 for exhausting air from the inside of the cleaning chamber 17 is provided in the upper portion of the front surface of the upper door 13, and the rear side thereof is shown in FIG. By providing the ribs 51 having the directionality shown in the drawing, when the upper door 13 is opened, the water droplets attached to the back surface are guided by the ribs 51 and flow down to the both sides, so that the dishes (not shown) are wetted with the water droplets. I try not to.

Next, the operation of the dishwasher having the above structure will be described. Now, as shown in FIGS. 1 and 3, the upper and lower doors 1
At 3, 14, the opening 12 on the front surface of the main body 11 is closed,
The case where the door is opened from the locked state held by the door lock mechanism 38 will be described. In this case, for example, when the power is turned “ON” on the operation panel 23, the LED 49 illuminates and indicates that the door is in the closed state via the door open detecting means 46, which will be described in detail later.

From this state, the user presses the push button 44 with his fingertip while holding the handle 45 with one hand.
Then, the base shaft 39 is rotated and the integrated hook lever 40 is also rotated against the tensile force of the tension coil spring 41 to move the hook portion 40a upward. As a result, the hook portion 40a is disengaged from the lower edge of the engagement opening 43a of the switch case 43, and the closing lock state of the lower door 14 by the door lock mechanism 38 is released. At the same time, one end of the actuator 48 constituting the door opening detecting means 46 abuts and engages with the stepped portion 40b at the tip of the hook lever 40 to release it from the previously depressed state, and thus swing. The end releases the pressing of the microswitch 47.

Along with this, the micro switch 74 is turned off, for example, to detect the open state of the lower door 14 (a state in which it can be opened at this point), and at the same time, the lock state by the door lock mechanism 38 is released. Is also detected, and the detection result is LE which is the display means of the lower door 14.
D49 is turned off (however, if the power is turned off, the LED 49 remains off from the beginning).

Continuing from that state, the user holds the handle 45.
When the lower door 14 is opened while holding the button, the interlocking mechanism 32
The lower arm 35 constituting the same is also centered around the shaft 31 and is indicated by an arrow A in FIG.
By rotating the upper door 13 in the closing direction, the wire 34 that has been in a tensioned state is relaxed by holding the upper door 13 in a closed state. Therefore, the upper door 33 is pulled in the closing direction via the upper arm 33. By being released, the upper door 13
The upper door 13 is opened and rotated to a predetermined position by the urging force in the opening direction due to the elastic force of the torsion coil spring 29 attached to the.

At this time, the interlocking mechanism 32 has the lower door 14
The opening degree of the upper door 13 is set to be larger than the opening degree of the upper door 13, and the lower door 14 is opened to a substantially horizontal position as shown in FIG. Let Then, in this open state, after accommodating tableware, chopsticks, spoons, etc., not shown, in the tableware basket 21 shown by the chain double-dashed line in FIG.
Slide it back inside. In this case, since the upper door 13 is wide open diagonally upward, it is possible to easily attach and detach tableware to and from the tableware basket 21.

Then, the door is closed again from this open state. In this case, if the user closes only the lower door 14, the upper door 13 is also interlocked via the interlocking mechanism 32. That is, the user turns the lower door 14 upward by holding the handle 45 and presses the lower door 14 toward the main body 11 side at the closed position which is substantially upright. During this time, the lower arm 35 of the interlocking mechanism 32 is returned and rotated in the direction opposite to the arrow A to pull the wire 34 connected thereto downward, and thus pull the upper arm 33.
Is rotated in the closing direction against the urging force of the torsion coil spring 29, and the upper door 13 is also rotated to a closed position where the upper door 13 hangs substantially upright. ,
It is closed by two doors 13 and 14.

At this time, in the door lock mechanism 38, the hook portion 40a of the hook lever 40 is elastically engaged and held by the tension coil spring 41 with the lower edge portion of the engagement opening 43a of the switch case 43, and the door opening mechanism is opened. In the detection means 46, the step portion 40b at the tip of the hook lever 40 abuts and pushes down against one end of the actuator 48, and this swinging causes the micro switch 47 to be turned on at the other end. As a result, the LED 49 on the front surface of the lower door 14 is lit and displayed, and a detection signal is input to the control device 26, and a standby state in which the operation can be started on condition that the closed state by the door lock mechanism 38 is normally locked. Let

However, now, the lower door 14 is not completely closed, and for example, the hook lever 40 of the door lock mechanism 38 on the right side.
If the lock is not completely held by, the micro switch 47 of the corresponding right side door opening detection means 46 does not turn on and remains off, so the right LED 49 remains off and the left side normally lights up display. With respect to the LED 49, it is clearly visible that the door lock mechanism 38 on the right side is incomplete.

Therefore, in this case, if the left side of the front surface of the lower door 14 is pushed toward the main body 11 side, the lower door 14 is surely brought to a completely closed state, and the door lock mechanism 38 also holds the normal lock. When the door opening detection means 46 turns on the micro switch 47, the L on the right side is activated.
The ED 49 lights up. As a result, the user can confirm that the above-mentioned malfunction has been effectively corrected, and can enter a standby state in which normal operation is possible. When the lower door 14 reaches the normal closed state, the upper door 13 is also interlocked with the interlocking mechanism 32 to be rotated to the normal closed position, so that the opening 12 is also formed in the two-door structure. It is securely closed and locked in that state.

At this time, if the power is turned off, the corrected LED 49 cannot be lit up. However, the operation key 2 of the operation panel 23 to be subsequently performed will be described below.
Since the setting operation of the washing course etc. including the power "turning on" at 4 is performed, it can be recognized in advance before the operation of the dishwasher and if there is a problem, it can be dealt with surely.
There is no problem.

After the doors 13 and 14 have been normally closed and held, a desired setting operation is performed on the operation panel 23 to start the operation. Control device 2
6 receives the input signals from the door opening detecting means 46 and the operation panel 23, and automatically executes the respective steps of "washing, rinsing and drying" in accordance with a prestored program. "Washing and rinsing" is performed by spraying water on dishes (not shown) with a washing mechanism having 19 or the like, and "drying" with a blower device using a blower (not shown).
The detailed description will be omitted.

As described above, the above configuration has the following effects. In this configuration, the door is composed of the upper door 13 and the lower door 14 and can be effectively installed in a kitchen or the like as a use space. In addition, the interlocking mechanism 32 allows the upper door to be opened and closed by simply opening and closing the lower door 14. Since 13 can be opened / closed in conjunction with each other, the opening / closing operation is simple and convenient.

In particular, in this structure, a plurality of door lock mechanisms 38 for maintaining a closed state are provided between the lower door 14 and the main body 11, and the lower door 14 corresponding to the door lock mechanisms 38 is provided. Is provided with an open door detecting means 46 for detecting that the door is in an open state, and an LED 49 as a display means for displaying the detection results of the open door detecting means 46, respectively.
Is provided. Therefore, even if the lower door 14 is closed, it does not reach the completely closed position, and the sealed state cannot be obtained for the opposing main body 11 side. The detection means 46 detects and the LED 49 displays.

Specifically, in the above-described embodiment, the light is displayed when the door is locked by the door lock mechanism 38 in the normally locked state, and the light is turned off when the door is incomplete. This not only indicates that there is a defect, but also which of the left and right side parts of the lower door 14
By visually observing whether or not 49 is lit (can be turned off), it is possible to confirm at a glance which part is defective. Therefore, if the operation for starting the operation is incomplete, the operation is not started, and it is rather wrongly judged that it is a failure. Such anxiety can be avoided.

Thus, even if the door lock mechanisms 38 are provided at positions greatly separated from each other on the left and right sides, the door can be reliably locked and held in the closed state, and excellent usability and smooth operation can be expected. Moreover, the LED 4 as the display means
Since 9 is provided correspondingly to the vicinity of each of the left and right door lock mechanisms 38, special accuracy and complicated means are taken as a display function for recognizing which position of the door lock mechanism 38 is defective. This is unnecessary, and an effective display function can be obtained with a simple configuration in which the LED 49 of the light emitting element is simply lit and displayed as in the present embodiment.

Incidentally, the door opening detecting means 46 in the above embodiment.
In other words, it can be said that it also has a function as a door closing detection means, but in the present embodiment, the door opening detection means 46 is used based on the intention of preventing the door from being completely closed and still in an open state. The LED 49 for indicating the detection result can be adopted by any means for turning on or off.

In contrast to the above-mentioned embodiment, FIGS. 4 to 12 show the second to eighth embodiments of the present invention. The same parts as those of the first embodiment are designated by the same reference numerals and their description is omitted. However, only different parts will be described below.

(Second Embodiment) FIG. 4 and FIG.
FIG. 6 is an enlarged view showing a second embodiment of the present invention and showing different operating states by breaking a part of a main part. This is different from the first embodiment in the display means for displaying whether or not the door is in the locked state indicating the open / closed state,
Others are in a substantially common configuration.

That is, FIG. 4 shows a state in which the door is locked and held at the closed position by the door lock mechanism 52 in the present embodiment, and the door lock mechanism 52 is arranged on both sides of the first embodiment. Only the hook lever 53 is different, but the difference is that the base end portion on the side opposite to the hook portion 53a only has, for example, a partially colored index 53c, and the shape is the same, and a step portion 53b is also provided at the tip. , Door opening detection means 4
6 and the actuator 48.

However, the lower door 54 provided with the hook lever 53 also differs in that the visible portions 55 constituting the display means different from those of the first embodiment are provided on the left and right side portions. That is, the lower door 54 is, for example, an outer door portion 54a forming the front side and an inner door portion 54b on the back side assembled in a hollow shape. In the part facing the index 53c,
A visible portion 55 made of a transparent hole or a transparent member is formed.

In order to make the indicator 53c provided on the internal hook lever 53 from the visible portion 55 easy to see, the indicator 53c is formed in an arc shape along the turning locus,
It has a bulged shape on the front side. Thus, in this embodiment, the indicator 53c and the visible portion 55 are combined to form the lower door 5 which is a door.
4 and display means for displaying the open / closed state of the interlocking upper door 13 and whether or not the lower door 54 is normally locked. The operation will be described below.

FIG. 5 shows the state immediately before the lower door 54 is closed (this is the same as the state immediately after the opening operation by the push button 44). The upper door 13 is also opened / closed in conjunction with this, but the upper door 13 is the same as in the first embodiment, and the description thereof is omitted. Then, when the lower door 54 is in the open state, the hook portion 53a side of the hook lever 53 is restricted to the position where it is pulled to the lowest position by being pulled by the tension coil spring 41, which is the lower door 54. As the closing movement proceeds, immediately before closing as shown in FIG. 5, the hook portion 53a slides on the lower edge portion of the engagement opening 43a and turns upward against the biasing force of the tension coil spring 41, One end of the actuator 48 is abutted and engaged with the step portion 53b at the tip.

Then, the hook portion 53a is engaged with the engaging opening 43a.
When the vehicle passes over the lower edge, it pivots downward to securely engage with the engagement opening 43a, one end of the actuator 48 is pushed downward as shown in FIG. 4, and the micro switch (not shown) is activated at the other end. To do. Therefore, the door opening detection means 46 detects that the lower door 54 is reliably closed and locked in that state, and inputs it to the control device (not shown).

On the other hand, the hook lever 5 which constitutes the display means
The index 53c applied to the item 3 was not visible from the visible portion 55 until immediately before the closing of FIG. 5, but it has moved to a position facing the visible portion 55 shown in FIG. This can be easily confirmed, and by this, it can be known that the lower door 54 is closed and the door lock mechanism 52 is normally locked.

On the contrary, when the above-mentioned locked state is incomplete, the indicator 53c cannot be seen from the visible portion 55 or only a part thereof cannot be seen because the hook lever 53 does not rotate to a predetermined position. Since it is in a perfect state, even in the case of such a defect, it can be immediately known, and since it is provided on both the left and right sides, it can be recognized at the same time whether the defect is on the left or right. As a result, like the first embodiment, even if the door is incompletely closed and there is a problem, it can be easily corrected and corrected before the operation is started, and the door can always be securely held in the closed state. , Easy to use and smooth driving can be expected.

(Third Embodiment) Next, FIGS. 6 and 7 show a third embodiment of the present invention. FIG. 6 is a view corresponding to FIG. 1, and FIG. Is. This also differs from the first embodiment only in the display means, and the display means is provided on the operation panel 56. That is,
The operation panel 56 has operation keys 24 for setting various courses and the like similar to the first embodiment, and a display section 25 for displaying the remaining driving time and the like.
The printing unit 5 that schematically prints and displays the front view, which is the front surface of 1.
7 is provided. As shown in an enlarged view in FIG. 7, the printing unit 57 includes a printing unit 5 according to the positional relationship of the door lock mechanism 38 arranged on both left and right sides (only one is shown) shown in FIG.
LEDs 58 are arranged on the left and right on the upper part 7. That is, the printing unit 57 may be a layout configuration diagram such that the positions corresponding to at least the plurality of door lock mechanisms 38 can be easily estimated, as in the front view of the main body 11.

Therefore, when the lower door 14 is closed,
The door opening detection means 46 has one of the left and right door lock mechanisms 3
When it is detected that the lock holding by 8 is incomplete, one of the left and right LEDs 58 on the printing unit 57 is turned on based on the detection result, and the other is off.
As a result, if it is displayed that the light-side lock is normally performed, it can be recognized that the door-lock mechanism 38 on the light-off side is incomplete, and the problem can be immediately corrected and dealt with.

Moreover, such display means can be easily known by the user by utilizing the easy-to-see operation panel 56, and
By assembling with the electrical connection wiring in the originally required operation panel 56 portion, the assembling work can be performed efficiently.
In particular, when the operation panel 56 is provided on the main body side as shown in this embodiment, there is no need for electrical connection wiring to the rotating door side, and there is an advantage that the configuration can be further simplified. still,
Although the LED 58 is used as the display unit, the electric light emitting unit is not limited to this and various electric light emitting units are conceivable, and as described above, the printing unit 57 has an arrangement configuration diagram in which the positioning of the plurality of door lock mechanisms 38 can be detected. It can be implemented with various modifications such as "good".

(Fourth Embodiment) FIG. 8 is a view corresponding to FIG. 1 showing a fourth embodiment of the present invention. In this embodiment, instead of the display means showing the open / closed state of the door so far, It is provided with a voice notification means. That is, this one also has the door lock mechanism 38 similar to that of the first embodiment, and is provided with the door closing detection means 59 which operates in association with this. The door closing detection means 59 has substantially the same configuration as the door opening detection means 46 in the first embodiment (the components are shown by the same reference numerals), but in this embodiment, the door is completely closed. This is different from the point that it is intended to detect that the door closing detection means 59 is used.

However, in the door closing detection means 59, when the plurality of door lock mechanisms 38 obtain the normal lock state and the micro switch 47 corresponding to these is turned on, the operation is performed based on the detection signal on the condition. Panel 60
The speaker 61 provided in the above is configured to give a voice notification. When the so-called lower door 14 is completely closed, a sound notification indicating that the operation is normal is made so that the user can immediately know and can immediately perform the next operation such as starting operation.

It should be noted that the notification time at this time can be prevented from being bothered by a long time notification by limiting the notification time to 5 seconds or less. In addition, in the above-described embodiment, when the micro switch 47 does not operate on either one of the left and right sides, when one of the so-called door lock mechanisms 38 is incomplete,
Even if it is easy to know that there is no voice notification and the closed state is incomplete, it is not clear which is left or right.

Therefore, if it is desired to know more detailed information, the application by voice notification is expanded, for example, a buzzer notification having different tones and tones according to the positions of right and left, or in any state by spoken language. By notifying,
More detailed detection information can be easily confirmed. In addition, it can be used in combination with the display means as in the first embodiment, and in such a case, it can be effectively confirmed and confirmed even when the voice notification is missed due to surrounding noise or the like.

(Fifth Embodiment) Next, FIG. 9 is an enlarged view of a partially broken essential portion showing a fifth embodiment of the present invention.
This is due to the bending deformation of the base shaft 39 and the hook lever 40 as one of the factors that lead to an unstable state where the door locking mechanism 38 is not reliably locked when the lower door 14 is closed. Is dealt with. That is, the lower door 1
Reference numeral 4 denotes a plurality of members integrally assembled or integrally fixed to the outer door portion 14a, which is composed of an outer door portion 14a forming the front surface of the outer door portion 14a and an inner door portion 14b forming the back side thereof. The shaft support member 62 (only one is shown) supports the base shaft 39, and thus supports the hook lever 40 and the push button 44 which are integrated with the base shaft 39.

More specifically, the shaft support members 62 are arranged at a plurality of positions along the left and right longitudinal direction of the base shaft 39, and the groove portion 6 extending inward from the outer door portion 14a side and having the open front end portion is opened.
It has a bifurcated shape sandwiching 2a, and a base shaft 39 is rotatably suspended between the plurality of groove portions 62a. Then, the opening side of the groove portion 62a is attached so as to be closed by the elastic plate 63, so that the base shaft 39 pivotally supported on the outer door portion 14a side can be rotated, and its deflection (play) is prevented as much as possible. In addition, the groove portion 62a is prevented from coming off from the shaft supporting side (the right side in the drawing).

According to this structure, the plurality of shaft support members 62 that support the base shaft 39 and the hook lever 40 against the external force in the direction of the arrow B, which is the front when the door is closed, are strong outside. Since it is provided on the side of the door portion 14a, the base shaft 39 and the hook lever 40 are easily supported without being bent, and therefore a normal locking operation of the door locking mechanism 38 can be expected.

By the way, the external force in the direction of the arrow B received when the door is closed is set by the hook lever 40 immediately before the door is closed.
At the position shown by the chain double-dashed line in the figure, the step 40b at the tip
Engages with one end of an actuator 48 that constitutes the door opening detection means 46. That is, the hook lever 40 is moved (rotated) in the direction opposite to the arrow B together with the lower door 14 and comes into contact with and engages with the actuator 48 when passing through the engagement port 43a. Due to the impact at that time, a relatively large component force in the direction of arrow B is generated in the hook lever 40. However, the shaft support member 62 fixed to the outer door portion 14a side as described above has sufficient strength to withstand the external force in consideration of the reaction force due to the impact, and in addition, the external force is exerted by the base shaft 39. Since it acts in the direction opposite to the opening side of the groove 62a to be inserted, the base shaft 39 is securely supported without the risk of slipping out, and the hook lever 40 does not flex and deform.

If the base shaft 39 bends in the direction of arrow B, the hook lever 40 naturally bends and deforms in the same direction. Then, the hook portion 40a is located at the position retracted to the left with respect to the engagement opening 43a of the switch case 43, and cannot be engaged with the lower edge of the engagement opening 43a even if it is rotated downward by the tension coil spring 41. Will occur a lot. Even if the so-called lower door 14 is closed, the completely closed state is not obtained, and the door lock mechanism 38 is also unable to normally hold the lock.

On the other hand, according to the present embodiment described above,
Even if an external force is generated in the direction of the arrow B at the time of closing the door, it is possible to prevent the base shaft 39 and the hook lever 40 from being supported on the outer door portion 14a side without bending, and avoiding the incomplete closed state of the lower door 14. The operability of the door can be improved and the user-friendly dishwasher can be provided.

(Sixth Embodiment) FIG. 10 is a view corresponding to FIG. 9 showing a sixth embodiment of the present invention. This embodiment is particularly devised based on the same purpose as the fifth embodiment. In contrast to the fifth embodiment, the hook lever 40 is pivotally supported on the outer door portion 14a side. As will be described later, the structure is pivotally supported on the inner door portion 64b side, and the hook lever 67 is provided with a retaining means.

That is, first, the lower door 64 has a hollow shape consisting of an outer door portion 64a and an inner door portion 64b, and a plurality of shaft support members integrally or integrally fixed to the inner door portion 64b side. 65 (only one is shown) supports the base shaft 66, and thus the hook lever 67 and push button 68 integral with the base shaft 66 are supported. Further, the shaft support members 65 are provided at a plurality of positions along the left-right longitudinal direction of the base shaft 66 similarly to the fifth embodiment, and the groove portion 65a opened at the tip end portion extending forward from the inner door portion 64b side. The base shaft 66 is rotatably suspended between the plurality of groove portions 65a. Then, the open side of the groove portion 65a is attached so as to be closed by the elastic plate 63, the base shaft 39 is rotatably supported, and its runout (play) is prevented as much as possible, and the base portion 39 is easily pulled out from the groove portion 65a. It is pivoted so that it does not exist.

On the other hand, the hook lever 67 constituting the door lock mechanism 70 is provided with a small protrusion 67c at the base end portion on the side opposite to the hook portion 67a, and the contact portion 69 which is the back surface of the outer door portion 64a. It is configured to be rotatable in a state of being in contact with. Therefore, the small protrusion 67c is composed of a sharp small protrusion having a minimum frictional resistance or the like, or a thin rib. In order to further reduce the frictional resistance, the outer door portion 64a itself is made of metal to reduce the frictional resistance with the contact portion 69 with which the small protrusion 67c is in sliding contact, or the contact portion 69a. It is effective to construct a separate metal member.

In such a structure, the base shaft 66 and the hook lever 67 receive an external force in the direction of the arrow B when the door is closed based on the same action as in the fifth embodiment, and the hook lever shown by the two-dot chain line in the figure. This is due to the abutting engagement between the stepped portion 67b of 67 and the actuator 48 of the door opening detection means 46, which acts until the hook portion 67a engages with the engagement opening 43a, and in particular a reaction force against the impact at the time of closing is applied and a large external force is applied. Is added.

In the case of the present embodiment, this external force is applied to the opposite shaft supporting side opposite to the side supported by the groove 65a of the shaft supporting member 65 because the base shaft 66 is supported on the inner door 64b side. It acts, and acts on the open side of the so-called groove 65a, and is easily removed. Although the elastic plate 63 elastically supports against this,
It is easily elastically deformed by receiving the above-mentioned external force, so that a large external force is applied particularly to the base shaft 66 portion near the hook lever 67,
As a result, it is easily bent and deformed in the direction of arrow B.

However, in this embodiment, the small protrusion 67c formed at the base end portion of the hook lever 67 has the outer door portion 64a.
Of the base shaft 66 and the shaft support member 65.
It is supported and fixed in a state in which movement in the direction of pulling out from the body is blocked. Therefore, the small protrusion 67c is attached to the contact portion 6
The contact with 9 serves to prevent the base shaft 66 from coming off with respect to a large external force generated when the door is closed, and exhibits a function as so-called coming-off preventing means.

In the present embodiment, however, as a result, the base shaft 66 and the hook lever 67 do not inadvertently move or deform, and the door lock accompanying the closing of the lower door 64, as in the fifth embodiment. The normal locking operation by the mechanism 70 is surely performed, and operability and usability are improved. The display means and the notification means disclosed in the first to third embodiments can be used in combination with the present embodiment, and in such a case, further improvement in usability can be expected.

(Seventh Embodiment) FIG. 11 is a view corresponding to FIG. 9 showing a seventh embodiment of the present invention, and particularly FIG.
The configuration is similar to that of the sixth embodiment disclosed in. However, the door lock mechanism 38 and the door opening detection means 46 have the same configuration as the first embodiment. That is,
In this embodiment, the lower door 71 includes the outer door portion 71a and the inner door portion 71b.
In the basic configuration in which the base shaft 39 is inserted and supported in the groove portion 72a of the shaft supporting member 72 protrudingly provided on the inner door portion 71b side, the so-called inner door portion 71b side is pivotally supported. The same as the embodiment.

However, the abutting portion 73 with which the outer periphery of the base end portion of the hook lever 40 is slidably contacted is, for example, a resin molding, and the outer door portion 7
1a is formed, and the periphery is formed to be thin to have a high elasticity, and in this case, it has an inwardly projecting form and is elastically connected to the arc-shaped outer peripheral surface of the base end portion of the hook lever 40. Abutting. In addition, on the front surface of the outer door portion 71a,
The decorative plate 75 is attached to cover the traces such as thinness of the contact portion 73 appearing on the surface so as not to spoil the aesthetic appearance.

Thus, when the lower door 71 is closed, while the hook lever 40 shown by the chain double-dashed line in the figure moves (rotates) to the position shown by the solid line, the operation of cooperation with the actuator 48 of the door opening detection means 46. Along with this, an external force is generated in the direction of the arrow B, and an external force is applied to the base shaft 39 toward the open side of the groove portion 72a that is the opposite shaft support side. However, the elastic plate 63 that opposes the external force is applied.
In addition, the hook lever 40 integrated with the base shaft 39 is received by the abutting portion 73, and the elastic force of the abutting portion 73 is stronger against the movement toward the opposite shaft supporting side in the arrow B direction. Is effective in preventing the movement.

Therefore, also in the present embodiment, as a result, the base shaft 39 and the hook lever 40 do not inadvertently move or deform, and the door locks when the lower door 71 is closed, as in the sixth embodiment. The normal locking operation by the mechanism 38 is surely performed, and operability and usability are improved. The contact portion 7
3 is not limited to the configuration in which resin is integrally formed with the outer door portion 71a,
It suffices to provide it in the lower door 71. For example, by making an elastic member, which is a separate member, elastically abut the hook lever 40, it is possible to reduce the frictional resistance when the hook lever 40 rotates. Substantially the same effects as those of the above configuration can be expected.

(Eighth Embodiment) FIG. 12 is a view corresponding to FIG. 9 showing an eighth embodiment of the present invention, and in particular, it has a shaft support structure similar to that of the sixth embodiment disclosed in FIG. It is common except that the retaining means are different. That is, in the shaft supporting structure in the present embodiment, the lower door 64 is composed of the outer door portion 64a and the inner door portion 64b, and in the groove portion 65a of the shaft supporting member 65 protrudingly provided on the inner door portion 64b side, In the structure in which the base shaft 66 is inserted and supported, a hook lever 74 integrally formed with the base shaft 66 is provided with a protrusion 74c as so-called retaining means protruding above the center of the base shaft 66.

When the lower door 64 is still in the open state just before the lower door 64 is closed, the hook lever 74 is provided with the step portion 7.
4b and the actuator 48 are in contact with each other in the state shown by the solid line in the figure, and the protrusion 74c provided at the base end portion on the side opposite to the hook portion 74a is the contact portion 6 of the outer door portion 64a.
It comes into sliding contact with 9 and there is no gap between it and the hook lever 74. Therefore, even if an external force in the direction of the arrow B is applied in this state, the protrusion 74c is in a state of being stopped by the contact portion 69, so that the hook lever 74, and hence the base shaft 66, is an anti-axial support in the arrow B direction. It is prevented from moving to the side, and the protrusion 74c functions as a retaining means for the base shaft.

However, the hook portion 74a is engaged with the engagement opening 43a.
Is engaged with the lower door 64 as a so-called door lock mechanism 76.
When it reaches a locked state in which is closed, the protrusion 74c moves upward (shown by a chain double-dashed line) by the rotation at this time, and separates from the contact portion 69 to form a gap. This means that, with respect to a large shocking external force (in the direction of arrow B) that occurs when the lower door 64 is closed, the protrusion 74c and the contact portion 69 come into contact with each other to support the hook lever 74 and the base shaft 66 in the opposite axial support. Side movement is effectively blocked, and then the hook lever 74
The frictional resistance with which the projection 74c is slidably contacted with the rotation of the engagement locks does not decrease, and the rotation for the engagement with the engagement opening 43c is smoothly performed to ensure the engagement lock.

As described above, the protrusion 74c serving as the retaining means in this embodiment is abutted and supported by the abutting portion 69 only at the so-called initial closing of the door, and then separated as it is engaged and locked. It is possible to eliminate the frictional resistance and the like by creating a gap, and by eliminating the rotation resistance of the hook lever 74 except when necessary, it can be expected to improve the operability of the door especially when the door is closed, As a result, it is possible to provide a dishwasher that can be smoothly started and is easy to use.

The present invention is not limited to the embodiments described above and shown in the drawings. For example, the interlocking mechanism provided between the upper and lower doors is not limited to the wire means but can be a link mechanism. However, the doors are not limited to those arranged vertically, but can be widely adopted in a door configuration in which a plurality of door lock mechanisms are arranged apart from each other. Can be carried out.
